RCurl，具有API密钥的基本身份验证 [英] RCurl, basic authentication with API key

问题描述

我曾经使用RCurl来获取需要登录的数据.现在，我必须使用api密钥(以及用户ID，密码)来获取数据，并且它需要基本身份验证(Radian6 api: http://socialcloud.radian6.com/docs/read/Getting_Started )

I used to use RCurl, to grab the data that needs login. Now I have to grab the data using api key (as well as userid,password) and it needs a basic authentication (Radian6 api : http://socialcloud.radian6.com/docs/read/Getting_Started)

如果不需要身份验证，则代码将类似于..

If it doesn't need an authentication, the code will be something like..

getURL("https:// address", userpwd="id:pswd", httpauth = 1L)

但是我不知道如何插入api密钥进行身份验证.到目前为止，我能够找到用python或Java编写的示例，但尚未找到R示例.谁能指出我正确的方向?我想知道如何使用RCurl进行基本身份验证，以及如何使用令牌来获取数据. (仅供参考，这就是python的工作方式:使用API​​密钥的Urlib2身份验证)

but I have no idea how to plug in api key for authentication. So far I was able to find examples written in python or Java but haven't found R example yet. Can anyone point me to the right direction? I'm wondering how I can use RCurl for basic authentication and how I can use a token to grab the data. (fyi, this is how python works :Urllib2 authentication with API key)

任何建议将不胜感激！

推荐答案

您可能会发现使用httr会更容易一些.代码看起来像这样:

You might find it a little easier to use httr. The code would look something like this:

library(httr)

req <- GET("https://address.com/authenticate", 
  authenticate("user", "pass", type = "basic"),
  add_headers(auth_appkey = api_key))
stop_for_status(req)
content(req)
# Then extract token etc
